Today's funeral services for fallen SFFD fire fighters Tony Valerio and Lt. Vincent Perez are expected to draw crowds of up to 5,000 to St. Mary's Cathedral at Geary Boulevard and Gough Street. This morning we've been spotting Fire Engines and Ladder trucks from pretty much every department in the Bay Area making their way up Divisadero for the procession that will stretch a couple miles long as it makes it's way from Cathedral Hill to Colma starting at 3:30 this afternoon. The services and procession will close streets throughout the Western Addition and Lower Pac Heights neighborhoods as well as part of Interstate 280. The complete list of street closures and Muni re-routes:

Traffic Alerts and procession route:

Interstate 280 Southbound will be closed between San Francisco and Daly City between 3p.m. to 7p.m.

Geary Boulevard westbound will be closed from Gough to Webster Street

Eastbound Geary closed from Divisadero to Gough.
